Alistair Darling did something rather strange recently, to baffling applause from his own backbenchers, and cries of “bribery” from the opposition: he announced a tax on teenagers.
Darling’s plan – for those who missed it – is to cut income taxes temporarily for all but the most prosperous taxpayers. The apparent windfall is £120 a head. A similar plan is already in place in the US, where a temporary “tax rebate” began to arrive in the bank accounts of a grateful nation about a month ago.
But there is no such thing as a free lunch: since neither the UK nor US governments plans to alter its spending plans, these tax holidays will be funded by government borrowing – borrowing that must eventually be repaid. That will require taxes to go up in the future, or not to fall when they otherwise might.
Who should celebrate? Not the typical taxpayer, that is for sure. The tax cut makes no difference to her. If she – assume she is British – had wanted an extra £120 right now, she could already have it in her pocket, either by withdrawing it from savings or by borrowing the money. If she did that, of course, she would later have to repay £120 plus interest. But that is exactly what Darling’s successor as chancellor will require of her. To look at it another way, the rational taxpayer should save the £120 windfall now, keeping it to pay the higher taxes that are surely on the horizon.
